Salting

"It is permissible to salt many pieces of meat together. So long as
a piece is still giving off tzir, it will not absorb blood from another
piece. Furthermore, even if tzir collects in a pocket between the pieces,
the meat is mutar." (Mechaber, Y.D. 70:1)

"Nevertheless, the custom is to
be strict l'chatchila concerning all pockets found in the meat. For example,
a side of beef should be turned over during the salting in order that the
blood will flow off, but b'dieved we do not need to do this." (Rama)
